of old church doors, which are said to have been made in very 
early times by sharpening spears and arrow heads before battles. 
One of these grooves was in the stone at the sides of the Union’s 
headquarters, the Robin Hotel, which is dated 1671. It was 
ascertained from an old inhabitant that half a century ago it 
was the practice of the schoolboys to “ make sand’ by rubbing 
a piece of stone against the soft sandstone blocks of which the 
houses and walls were built. Thus another antiquarian mystery 
was solved. 
On the Monday morning the party followed the course of 
the trout-laden stream in Danby Dale as far as the residence 
Mr. G. A. Macmillan, who kindly conducted the members around 
his well-arranged gardens. From here the party went over the 
moors via Great Fryup Head and George Gap Spa to Trough 
House, thence over broken ground to Fryup Head, through 
Little Fryup Dale, by Danby Castle, and back to Castleton. 
In this long and varied route all the sections found something to. 
occupy their attention. A slight detour was made to visit Danby 
Church, where the late Canon Atkinson preached for many years. 
After tea a meeting was held, at which the representitives 
of the various sections gave reports on their investigations. 
Mr. J. J. Burton, F.G.S., presided. Votes of thanks were passed 
to Lord Downe, Lord Boyne, Mr. Macmillan, Mr. R. B. Turton 
and others, for kindly giving permission to visit the estates, 
and to Messrs. J. J. Burton, F. Elgee and J. W. R. Punch for 
acting as leaders. Mr. Elgee was especially thanked for the 
excellent local arrangements. An important resolutoin was 
unanimously passed, strongly protesting against the utilisation 
of the ground which has for so long been set apart for an exten- 
sion of the natural history museum at South Kensington, for 
any other purpose ; and urging the Government to reconsider 
its proposal with reference to it.—T.S.

Photography for Bird Lovers, by Bentley Beetham, F.Z.S. Messrs. 
Witherby & Co., London, 5/- net. 
This book, in its nine chapters, deals in a thorough, efficient, and 
practical manner with all phases of bird photography. No space is wasted 
in dealing with the practice of photography itself, it being taken for 
granted that the reader is grounded in the rudiments of the science. Good 
advice, however, is given upon the choice of apparatus, though the remarks. 
upon lenses might, with advantage, have been carried further. Photo- 
graphing nests and young birds, the various methods adopted for con- 
cealing the camera and operator, are well explained ; and some good hints 
are offered with regard to cliff work; and here the writer does not fall 
into the regrettable habit of some of his fellow-photographers, who delight 
to dwell upon the supposed dangers of this work. Interesting, if short, 
chapters are included upon colour-work and cinematography, though 
the latter is out of the reach of the ordinary amateur. Photographing 
birds in flight, and in captivity, are also dealt with in an efficient manner. 
The book is illustrated by some choice examples of the author’s work, 
and can be thoroughly recommended to anyone interested.—R.F.
